java -> 无法找到 com.google.android.exoplayer :exoplayer-core:r2. 4.2

Question

更新项目依赖项后，我在视频 android studio 应用程序中遇到这个 exoplayer not found 错误。

我不知道如何将旧的 Exoplayer 链接更新到 https://mvnrepository.com/artifact/com.google.android.exoplayer/exoplayer

谁能告诉我如何消除这个错误并更新到最新的 exoplayer 版本？

Answer 1

将这些添加到 build.gradle 后工作:

implementation 'com.google.android.exoplayer:exoplayer-core:2.15.1'
implementation 'com.google.android.exoplayer:exoplayer-dash:2.15.1'
implementation 'com.google.android.exoplayer:exoplayer-ui:2.15.1'

并启用 multidex。
